M12 Wide Angle Lens Applications

Core Application Scenes

This 5MP M12 wide angle lens is designed for camera systems that need to capture a broad area from a short installation distance. Its 146° diagonal and 110° horizontal field of view make it particularly suitable when conventional fixed focal lenses would leave excessive blind spots.

For robotics vision, the 3.1mm focal length provides a broad perspective for mobile robots, compact autonomous platforms, and indoor service robots. The 0.1m minimum object distance is especially useful when cameras need to observe objects or obstacles at close range while maintaining substantial surrounding coverage.

The lens is also suitable for compact smart security cameras and indoor monitoring devices. Its wide viewing angle can help cover entrances, corridors, retail areas, equipment zones, and other confined spaces with fewer cameras. The 5MP resolution provides additional image detail compared with lower-resolution wide-angle modules.

In embedded vision applications, the compact M12 lens configuration makes it practical for integration into small camera housings, AI edge devices, and customized imaging modules. Engineers developing M12-based systems can explore the broader M12 Lenses range for alternative focal lengths and optical configurations.

Designed for close-range wide-area monitoring, compact robotics vision, and embedded panoramic imaging applications.

Because this lens combines a 1/2.5″ image format with a 3.1mm focal length, engineers should verify sensor coverage and required field of view before selecting the final configuration. TOWIN’s Sensor Guide provides guidance on sensor and lens matching, while the FOV Calculator can help estimate coverage based on sensor and installation requirements.

For applications where lens selection depends on working distance, sensor size, and required coverage, the Lens Selection Guide can be used as a reference during optical system design.

Frequently Asked Questions

• Q: What type of lens is this 3.1mm M12 lens?
  A: It is a 3.1mm fixed focal M12 wide-angle lens with a 146° diagonal field of view, designed for compact systems requiring broad scene coverage.
• Q: What sensor size is compatible with this M12 lens?
  A: The lens is specified for a 1/2.5″ image format and provides a 5MP resolution specification. The complete camera assembly should be verified for sensor compatibility before production.
• Q: What is the field of view of this lens?
  A: The specified field of view is 146° diagonal, 110° horizontal, and 82° vertical, providing extensive coverage from a compact 3.1mm focal length.
• Q: Is this lens suitable for close-range imaging?
  A: Yes. With a minimum object distance of only 0.1m, the lens is suitable for applications that require wide-area coverage at relatively short working distances.
• Q: Is this a low distortion M12 lens?
  A: No. Its optical distortion is specified as less than -64% diagonal, -37% horizontal, and -20% vertical. This level of distortion is characteristic of an ultra-wide optical design rather than a low-distortion lens.
• Q: What applications are suitable for this 5MP wide-angle lens?
  A: It is suitable for robotics vision, compact security cameras, indoor monitoring, embedded vision, smart IoT cameras, and other systems requiring broad visual coverage.
• Q: How do I select the right M12 lens for my camera?
  A: Lens selection should consider sensor size, focal length, working distance, field of view, resolution, and mechanical requirements. TOWIN’s Lens Selection Guide can help engineers evaluate these factors.
